The strong team of four went down the Prod’s Pot carrying a set of diving tanks (7l and 2l), harness with 3.5kg of lead, reel with 80m of line, set of fins and 4 masks. We were all in wetsuit.
Our goal was to investigate the second sump in Formation Passage which I believed at the time been undived. Only after the trip I discovered that it’s been dived by Solari and Elliot but found to be too tight. The main reason I was interested in it was the fact that the water issuing from Formation Passage was dye traced from many surprising and remote places.
At the first the Sump 2 looked very promising - the underwater passage was descending along fine gravel bottom. Unfortunately it was too low to enter, the clearance between the roof and the bottom being only 25cm. However it turned out to be extremely easy dig since the gravel, once disturbed, was carried away by the flow out of the sump. After 15 min of digging or so the progress of some 4m was made and the passage was seen to continue descending. There was no time for any lengthy excavations though – to get there took us more time than we had expected and we needed to hurry to get out before the callout.
